Variant summary

Our verdict is Benign. The variant received -9 ACMG points: 0P and 9B. BP4_StrongBS1_SupportingBS2

The NM_005089.4(ZRSR2):c.283G>A(p.Ala95Thr) variant causes a missense change. The variant allele was found at a frequency of 0.000529 in 1,193,897 control chromosomes in the GnomAD database, including 4 homozygotes. There are 178 hemizygotes in GnomAD. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as not provided (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A95V) has been classified as Uncertain significance.

Genes affected

ZRSR2 (HGNC:23019): (zinc finger CCCH-type, RNA binding motif and serine/arginine rich 2) This gene encodes an essential splicing factor. The encoded protein associates with the U2 auxiliary factor heterodimer, which is required for the recognition of a functional 3' splice site in pre-mRNA splicing, and may play a role in network interactions during spliceosome assembly.

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -9 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.0044573843).

BS1

Variant frequency is greater than expected in population eas. GnomAdExome4 allele frequency = 0.000531 (575/1083604) while in subpopulation EAS AF = 0.0166 (491/29652). AF 95% confidence interval is 0.0153. There are 3 homozygotes in GnomAdExome4. There are 162 alleles in the male GnomAdExome4 subpopulation. Median coverage is 30. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
